Prelab:

For the Prelab the students were tasked at making a NAND gate with two inputs from tutorial 4.

After making the schematic view the layour was created with no DRC errors and with the LVS net lists matching

To ensure that the NAND gate was working correctly simulations were done showing that the truth table held true.

Lab:
For the lab the first task was to create a xor gate using the schematic image that was provided in the lab description

After making the schematic the next step was to create a symobl for the XOR gate with our name and semester we built it in.

Following the symbol the layout was made with no DRC errors, and with the LVS netlists matching.

After making sure that the netlists match an A and B input were given to the XOR gate to test the output of the XOR to ensure that it was working correctly.

Now that all of the gate components were made the following step was to make the full adder schematic.

After the schematic was made the Layout view was constructed with no DRC errors and with the LVS netlist matching.
